I'm so sorry about Lucas. Five visible tumors is definitely not encouraging. At this stage the steroids probably won't do any harm and will probably make him feel better.

Not to hijack, but I have to put in two cents about chemo. I've had two cats go through it. The value of chemo very much depends on the kind of tumor. In both cases it had minimal quality of life effect on the cat. Pink Nose did not even lose a single whisker.

{{Hugs}} to you and Lucas.
